2 Claims.

Another object of the invention is the pro-.

vision of a construction of the character indicated so constructed and arranged as to facilitate the proper shaping of a shoe and fitting of the sole thereto.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification and in which Fig. 1 is a side view, shown partially in section, of a machine or appliance embodying the in- Vention;

Fig. 2, an enlarged partial top plan View of the same;

Fig. 3, an enlarged side view of the main portion of the construction;

Fig. 4, a front view corresponding with Fig. 3;

Fig, 5, a horizontal section taken substantially on line 5-5 of Fig. 4; and

Fig. 6, a longitudinal section corresponding with Fig. 5.

The embodiment of the invention illustrated in the drawings comprises a suitable supporting frame I generally in the form of a table. A vertical last spindle II is arranged as shown on the top of said table II] adjacent the front edge thereof. The spindle II is carried by the base block I2 vertically slidable on a post l3 on a second base block |3 secured as indicated to a plate It! mounted on top of the table I0. Associated with the spindle II is a laterally swinging hand lever I4 carrying an inclined cam plate l5 arranged to be inserted as shown between the supporting base I2 and the base l3 to adjust the former vertically on the post I3.

The spindle II is arranged as best shown in Fig. 6 to receive a shoe last I6 of usual construction and carrying a shoe I! in the course of manufacture, said shoe last being provided with a socket I8 to receive the upper end of the spindle II, said shoe last and shoe thereon thus being rendered vertically adjustable on the spindle II by means of the cam plate I5 as will be readily .understood.

Associated with the spindle H is a swinging arm |9 hinged as shown to the top of the table provided at its upper end with a padded toe support 2|] adapted and arranged to be adjusted to the toe portion of the last I6 to support the same and the shoe thereon during the lasting operation. For convenience of adjustment the base block I3 and the arm I9 are both mounted on the adjustable plate III which is adjustably mounted in suitable guides on the table top and the arm I9 is further rendered adjustable on the plate I0 by means of a pin I9 adapted and arranged to engage spaced openings in the plate if) as best shown in Fig. 6.

Two laterally swinging clamping plates or wipers 2| are arranged as shown on opposite sides of the last I6, each clamping plate being provided with a curved edge 22 nicely shaped as best shown in Fig. 5 to the contour of the corresponding sides and around the heel of the shoe on the last. The clamping plates 2| are secured as shown in slots in clamping levers 23 pivoted at 24 opposite the central part of toe portion of the last and whereby said clamping plates 2| are arranged to swing toward and away from the last in planes just below the welt of the shoe on the last. At their forward ends the clamping levers 23 are provided with inward extensions 25 connected with handle members 26 arranged to be secured together in their innermost portion by a latch member 21 as best shown in Fig. 2. By this arrangement a shoe member on the last |6 may be readily clamped to the last by means of the clamping plates 2| and said clamping plates securely locked in clamping position as will be readily understood.

A clamping loop in the form of a flexible wire 28 is arranged as shown to embrace the toe portion of the shoe just under the welt, the ends of said loop passing thence downwardly through slots 29 in the edges of the plates 2| around the guide member 3|! in guide grooves 3| and are connected at their lower ends with a belt 32 which in turn is connected with a foot lever 33 and whereby the wire loop 28 may be tightly drawn about the last in order to hold the shoe member in proper position thereon.

In use and in operation a pre-welt shoe comprising the usual upper, insole and welt are preferably secured to the last I6 by nails and said last is then placed on the spindle II and nicely adjusted thereon until the plane of the clamping plates 2| is arranged to pass just under the welt of the shoe. The edges of the plates 2| are then fitted around the shoe just under the welt, the wire loop 28 fitted around the toe portion of the shoe also just under the welt and said clamping plates and wire loop simultaneously tightened about the shoe to shape and hold the same in place on the last as will be readily understood by those skilled in the art. Owing to the fact that the clamping members are pivoted at points opposite the central part of the toe portion of the last, the portions thereof shaped to fit the..shoe sides. arefirst brought into positive clampingyengagement therewith .so as to secure the uppers at these points, 'before the stretching action of the upper around the heel iscompleted thus greatly facilitating a close fit at the sides. Then when:tlie flexibleiloopiistight ened around the toe portions,..these portions of the upper are stretched "forwardly from the side"- portions thus greatly facilitating a smooth fit at" the toe portions. Then the nails securing the in sole in place on the lastare"withdrawn fiadh'esive' is applied to the insole and welt and the outer shoe sole applied by heavy pressure and pound 1 ing :to beiaccurately and nicely secured in place.

x andxheavy pressure andupounding is permissible for the purpose of;'building.-.the.;shoe properly ferred. form of construction for carrying the invention into efiect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of the con struction set forth, but desire to avail myself of such variations and modifications as fall within the. scope of. the appendedmlaims. i claim:

1. A device of the class described comprising ..a shoe last support; a pair of clamping members positioned on opposite sides of and pivoted ,atpointszoppositethe central part of the toe portion of-the.support to swing toward and away from the same and shaped to fit the corresponding shoe sides and aro'und the heel thereof; means for forcing said clamping members toward said support;-=meansfor -locking said clamping members in. clamping positions; a loop of flexible material arranged to embrace the toe portion of a =1shoe;.' and .means for drawing said loop tightly around: the toe. portion of the last support. 2-1. device of the class descm'bed comprising eiaxshoe lastisupport;..a pairof clamping members positioned onnoppositemsides of'and' pivoted at points opposite the central part ofthe-toerporwtion of-xthecsupport .to swing-toward iandaway ilromthezsame:and.shaped 't'o fitthe corresponding shoezsides and: around the heel thereof; -means for forcing said :zcl-amping membersxtoward said support; means for locking said clamping members in clamping positions fa loopiof' flexible maowing to. the. proper adjustment :ofthe-last per-. ."zterial :arranged .toembrace the toe portion of the rmitted by themechanismiand the presenceof the adjustable 'padded toe rest disclosed.
